In actual production, different phosphating treatment methods must be selected according to different uses of phosphating steel wire for optical cable. According to their practical experience, the company puts forward the following suggestions: for the surface treatment of wire rod, dip phosphating can be selected; for the follow-up processing, online phosphating can be selected for the semi-finished steel wire with the diameter of 1.5-2.5mm drawn by the water tank; for the follow-up processing, electrolytic phosphating can be selected for the semi-finished steel wire with the diameter of 2.5-4.0mm drawn by the direct type dry drawing.

With the development of non cyanide electroplating technology and the continuous improvement of technology, as a low energy consumption, less pollution, high output alternative product, it has been widely recognized by the society, the product sales channels continue to expand, its use has been extended from a single mechanical manufacturing field to the life field, such as: spring, wire, rope, crafts, decorative products, etc., the market prospect is good.

The good quality of steel wire lubrication coating is an important condition to ensure the normal drawing of steel wire, especially in high-speed drawing, high-quality lubrication carrier is very important, which is related to the surface quality, mechanical properties, die consumption and labor productivity of steel wire after drawing. At present, phosphating is widely used in the production of metal products as the surface pretreatment before wire drawing.
